The
OEM BPV valve was mounted onto the end tank of the intercooler:
A
shroud was fabricated to scoop air from underneath the car:
The scoop from the inside:
The
rear honeycomb between the taillights was cut out to allow air
to leave the trunk:
90 mm Infiniti Q45 throttle body all hooked up with
Turbohoses silicone and some constant-tension worm-drive clamps:
Idle
control valve was relocated, another view of the BPV and one of
the SPAL fans can be seen here:
Hydra
Nemesis EMS and the Aquamist water injection and relays can be
seen here:
....
and the final set up looks like this:
With
the GReddy side-mounted intercooler we would see intake temps
(in the intake manifold) over 150 degrees at the end of a drag
race. With this set up we just pass 93 degrees on an 80 degree
day!
All
of this work resulted in 440 rwhp @ 22 psi and 424 rwhp @ 20 psi.
This was up from the previous 384 rwhp @ 20 psi with the GReddy
side-mounted intercooler. That's a 40 rwhp gain from the
intercooler & throttle body!
The
final 20 psi and 22 psi dynoes are here:
This
is the 20 psi dyno overlaid with the 20 psi graph with the
GReddy intercooler:
